STM32 Audio class USB not recognized as audio device ...
https://electronics.stackexchange.com/questions/203143/stm32-audio-class-usb-not-recognized-as-audio-device
buffer[AUDIO_TOTAL_BUF_SIZE] AUDIO_TOTAL_BUF_SIZE = AUDIO_OUT_PACKET * AUDIO_OUT_PACKET_NUM AUDIO_OUT_PACKET_NUM = 80 AUDIO_OUT_PACKET = (22100 * 2 * 2)/1000 So total memory allocation size is about 7100 bytes. I set heap size in CubeMx project 10KB (2800h). After that windows (I use win10) recognizes stm32f4 as audio device.
